Repositories The use of git allows people to contribute changes that can easily be incorporated back into the project, while maintaining order and consistency in the code. All changes should be tracked and reversible.

Packaging

Issue tracker It has forum on which you can ask your question.

New contributor On the GitHub provides a straightforward way for collaborating on a project. More information how to contrabute you can see on the folowing page: ​http://osdoc.cogsci.nl/3.1/dev/howtocontribute/

Community norms You can create a fork of the central OpenSesame repository. You can also create a local clone of that fork: for small changes(make the changes directly in the master branch, push back to your fork, submit a pull request to the central repository) and for substantial changes (create a branch, when finished run unit tests, when the unit tests pass merge changes back into the master branch, submit a pull request to the central repository).

User base It has its own strong user base.
